I was hoping that the "child" command being run there gives enough
clue before the warning message so that the user would already know
(that is where my "assures the users" primarily comes from---even we
cannot hide that the negotiation poll has failed, the users would be
helped by being told that it is OK).

If "child" does not give enough clue to this codepath (via the exit
code) or to the end user (via error messages), we probably would
want to fix that for that approach to work.
